Does anyone make their own fish food?

[RyanScanner]

I just trying to suss out alternatives to my way as I’m just guessing and use anecdotal methods gleamed from forums and google.

Is it easy to grow? Probably a way better more natural option to thicken.

cut a little finger of the spikey algae, stab it through a twisted laid-line (rope) and buoy one end of the rope to keep it off the bottom. If nobody steals it in the meantime, come back in 6mo & you'll have more than you can use.
so... yes, easy.

Is there any advantage to using agar instead of gelatine.

I find agar easy as to use. Just mix some with some water and your done pretty much. Binds well but fish can still tear it up
